Abstract:
An assembly for actuating a synchronizer includes a shift fork, a shift rail, and a permanent magnet connected to the shift rail. A first control coil is disposed in proximity to the permanent magnet. The first control coil is operable to produce a magnetomotive force on the permanent magnet in a first direction when a current is applied to the first control coil. A second control coil is disposed in proximity to the permanent magnet. The second control coil is operable to produce a magnetomotive force on the permanent magnet in a second direction when a current is applied to the second control coil. The permanent magnet is moved to a first position when the current is applied to the first control coil and the permanent magnet is moved to a second position when the current is applied to the second control coil. Movement of the magnet in turn moves the synchronizer between engaged positions.
